To all whom, it may concern.-

Be it known that I, WILLIAM M. DUOKER, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented certain new and useful Improvements in Roofs for Houses, of which the following is a specification.

This invention relates in the main to the.

class of structures known as portable houses, where the parts oing to make the house are constructed and fitted at the factory, so that they may be assembled on the site where the house is to be set up or erected. The present invention has relation to the roof or covering of a house and the manner of rendering said roof fireproof or proof against ignition rom sparks and the like.

In the accompanying drawings, which illustrate an embodiment of the invention as v.applied to a portable house, Figure 1 is a sectional view, the plane of the section being vertical and through the roof from the ridge lower en the house 2, the wa to the eaves. Fig. 2 is a side elevation showing the roof-sections without the metal covering, and Fig. 3 is a similar view showing the same with the sheet metal in place thereon. Fig. 4 is a fra mentary sectional detail showing the bolt which secures the roof-sections in position. Fig. 5 is an illustrative detail view showing the means for drawing together the roof-sections laterally. Fig. 6 is an en 'larged detail view of the ribs on the roofplates and the batten. Fig. 7 is a similar view to Fig. 6, illustrating a construction where the metal covering-plates are put on the roof-sections before they are laid.

1 designates the u right siding sections of l-plate resting thereon; 3 the beveled plate resting on thewallTplate to receive the roof, and 4 the roof-sections, which will usually be of uniform width and extend from the eaves to the ridge, where they abut and are secured together by suitable interlocking metal fastenings 5. The sections are notched onto the plate 3 (at 6 in Fig. 1) and are secured to the plate 2 by a T- headed bolt 7. (Seen enlar ed in Fig. 4.) This bolt passes down througl i the wall-plate and through the upper transverse member of the sidin section 1, and it has a nut on its 5 to draw it down firmly and bury the prongs 7 a on its head into the wood of the adjacent roof-sections, as shown. The roofsections are held together at intermediate points in their length by means best seen in Figs. 2 and 5that is to say, the meetin edges of the roof-sections are sli htly beveled and in each is set or driven aioolcheaded nail 8', with the hooks thereof turned in 0p,- posite directions in the adjacent sections. The roof-sections when bein placed are turnedup to the position seen in ig. 5. Aring 9, out from or formed of metal, is placed so as to engagethe hooks on the nails and the sections again placed or pressed down flat, as in Fig. 2. This device serves to draw the roofsections singly together, edge to edge.

The roof-sections are framed and made ready atthe factory, and after they are laid each is covered with a plate 10, of sheet metal-as galvanized iron, for example, constructed as shown best in Figs. 3 and 6that is to say, the sheet has an outwardly-turned overhanging rib 11 formed along each of its lateral margins and.extending len thwise of the sheet. This rib is produced, pre erably, by

folding the metal, as clearly shown in Fig. which represents a section of part oftwo adjacent sheets on a relatively large scalethat is to say, the metal of the sheet is folded on itself to form two closely-applied plies or thicknesses.

Along the margin or edge of the metal sheet exterior to the ribs 1 1 are formed perforations12 to receive nails 12 for securing the sheet to the roof-section. v

When the sheets are laid on the roof-sections and secured, the joints between adjacent sections are covered by sheet-metal battens13, which have their lateral margins 13 turned under to engage the overhanging ribs 1 1 on the sheets 10, as shown. These battens extend from the eaves up to the ridge and along the ridge is placed a sheet-metal rid eroll 14. (Seen in Fig. 1.) This roll will be tted closely to the sheet metal of the roof and may be secured by soldering or other means.

Preferably sheets of asbestos will be inserted between the sheets of metal 10 and the wood of the roof-sections 4. This is seen at 15 in Fig. 6.

It may be explained here that the roof-section of wood may be constructed in any convenient manner-for example, it may have side bars connected by transverse members and be covered by matchedboards, as illustrated in my pending application, Serial N 0. 188,691, and the metal-locking devices 5 may be the same as shown in my said application.-

These features form no essential part of the present application.

In Fig. 1 is shown an inner ceiling forming v a part of the roof and sloping therewith, there in the wall-plate at 20. To insure a being an air-space'and air circulation between the roof proper and said ceiling. This feature is not specifically claimed herein, but is embodied in an application which is adivision of the present one. It will therefore be only briefly described herein. In constructing this-ceiling, as shown in Fig. 1, there is employed a ridge-plate 16 and intermediate plate 17, both of the desired width, and these extend lengthwise of t e building parallel with the beveled wallate 3. These plates 16 and 17 are provided with cleats 18 to support ceiling-boards 19 of matched stuff, the lower extremities of which engage a groove free circulation of air in the space between this ceiling and the roof-sections, the plates 3, 16, and 17 are perforated or apertured, as seen It has been stated that covering-plates are put on the roof-sections after the latter are placed, and this may of course be done; but they may also be covered at the factory. In Fig.7 this mode of operation is illustrated. In this construction the metal sheet is somewhat narrower than the roof-section and does not extend uite to the lateral margin of same and the l)olt 7 and nails 8 are disposed between the edges of adjacent metal plates and covered by the batten 13.

Having thus claimi 1. A'portable house, having its roof composed of roof-sections of wood, extending from the ridge to the eaves, said sectio'ns'each having its edges beveled as shown and prodescribed my invention, I

40 vided along said edges with headed nails,

the sheet-metal rings which engage the headed nails on adjacent roof-sections when the latter are tilted until their beveled edges match and which draw the sections securely together edgewise when the latter are laid flat, sheets of metal which cover the respective sections, and each of which is secured along its lateral margins to therespective margins of the sections, said sheets each having two longitudinally-extending ribs near its respective mar' ins, formed by folds of the metal and curve toward each other, and flat, flanged battens of sheet metal, the flanges of which engage the ribs on adjacent roof-sections and cover the joints between the said sections.

2. A portable house, having its roof-covering composed of sections made from wood, and each section provided with a fireproof covering composed of sheet metal provided with an inner lining of asbestos and secured to the wood, the metal sheet having near each edge a longitudinal rib of two thicknesses or plies ofthe metal, and having in its margins, exterior to said ribs, holes to receive securing devices and flanged battens of sheet metal to engage the ribs on the plates and cover the joints between the sections.

3. A portable house, having its roof-cover-. ing com osed of wood roof-sections beveled at their ateral edges, the rin s 9, for securing 7n the sections together, and t e hook-headed nails 8 in the sections to engage said rings.

In witness whereof I have hereunto signed my name, this 20th day of December, 1904, in the presence of two subscribing witnesses. 7 5
